It wasn’t good work. They needed to add another ground bus bar, but it is a much bigger job than simply adding a circuit. That is why they pigtailed the neutrals. If they were smarter, they would have pigtailed a few grounds and bonded that to the bar. The current normally flows through the neutral so the load on the ground is negligible if anything.
